Even though their voice is one of the most important tools for conveying information, lecturers often lack knowledge of its proper and effective use. A permanent incorrect use can result in chronic voice problems like e.g. a sore throat, hoarseness and even occupational incapacity. For this reason, many universities offer voice trainings. The environment of those trainings, however, often does not allow for a realistic simulation of large lecture halls and side effects in terms of noise and other disruptions. This problem is addressed within the context of the cooperative project "ELLI2" - Excellent Teaching and Learning in Engineering Science. The developed Mixed Reality-Voice Lab (MR-Voice Lab) integrates visual and acoustic data from real lecture halls into a specially developed Mixed Reality scenario. This gives lecturers the opportunity to participate in immersive voice trainings, where they can train their voice in a virtual setting that is both an acoustic and visual realistic simulation of their everyday teaching environment. The latest prototype of the MR-Voice Lab comprises six different rooms of various sizes. To generate these settings, real lecture halls have been visually captured by using 360° cameras and acoustically traced, based on their original construction plans. The acoustic and visual immersion of the participants is enabled by the use of VR headsets, headphones and a microphone. While the lecturers apply the methods learned in a safe and realistic virtual environment, they are guided and provided with direct feedback by a professional vocal coach. This paper describes the conceptualization of the MR-Voice Lab and contributes to answering the question whether Mixed Reality constitutes a reasonable addition to classical voice trainings. Hereby, the authors refer to their specialized knowledge regarding the special aspects of teaching and learning in Mixed Reality as well as to their background as speech and language pathologists. The implementation of the Lab will be thoroughly evaluated and constantly adjusted towards the needs of all parties involved. In the future, the open source MR-Voice Lab will be applicable to other universities and in additional contexts. [ABSTRACT FROM AUTHOR] |
